1.109,799 Specification of Letters Patent.

No Drawing.

To all whomit may concern:

Be it known that I, GEORGE W. SNYDER, a

citizen of the United States, residing at Los Angeles, in the countyof'Los Angeles and State of California, have invented a new and usefulWaterproofing Material, of whlch the following is a specification.

This invention relates to a material for waterproofing cement, concrete,wood, cloth or other materials, and the main object of the invention isto provide a material in the form of a solution capable of applicationto the surface to be waterproofed, and serving to render the surfacewaterproof at a minimum of expense, or the material may be incorporatedwith cementin the process of manufacture.

The waterproofing material or prepara: tion constituting my inventionconsists essentially of aluminum soap containing an excess of fat orsaponifiable wax,'said excess fat or wax being emulsified with the soapand the material also containing alkali and sulphur, and I also preferto use an adhesive substance as one of the ingredients, for example,glue, gelatin, or-'other mucilaginous substance, together with apreservative therefor. The material is prepared in the form of asolution with a suitable solvent, preferably water.

The saponifiable or fatty constituent of the soap preferably consists ofa saponifiable wax, such as Japan wax, or it may consist of any suitablefat or mixture of wax and such fat.

The alkali and sulphur is preferably added in the form of a solutionherein called the lye-sulfur solution, the formula for the preparationbeing as follows: Sodium hydrate (98%) 1 to 3% 1b., Japan wax 20 to 281b., lye-sulfur solution gah, glue 20 to 24 1b., alum 3 to 16 1b.,potassium nitrate 2 to 4 1b., water, sufiioient to make 100 gallons. Theformula for the lyesulfur solution is as follows: sulfur 5 1b., sodiumhydrate 30 02., water 5 gal.

The method or process of preparing the complete solution may be carriedout as follows: The 'wax or other fatty material Application filedAugust 5. 1912. Serial No. 713,470.

is saponified by boiling with a solution of alkali such as caustic sodaor potash. the

an excess .of wax which is emulsified by the soap formed. The solutionresulting from the saponification .is then mixed with the lye-sulfursolution in the proportions above stated and with the glue and the saltof aluminum, for example, alum is then added. The potassium or sodiumnitrate is then added as a preservative. The solution of alkali maycontain water .in proportion of about thirty gallons to the quantity ofalkali above given. The glue is added in the form of a solution, sayabout fifty gallons of water to the amount of glue above given. The alummay be added dry or in solution, in water. In place of alum, I may useany other salt or aluminum which is soluble in the water or solvent usedin the process.

The waterproofing solution prepared as above described contains in eachone hundred gallons of solution in water, 1.2 to 3.7 pounds of sodiumhydrate, 20 to 28 pounds Japan wax, pound sulfur, 20 to 21 pounds glue,3 to 16 pounds alum, and 2 to 1 pounds potassium nitrate.

lVhat I claim is:

1. A waterproofing solution containing in each one hundred gallons ofsolution in water, 1.2 to 3.7 pounds sodium hydrate. 20 to 28 poundsfatty material, 1} pound sulfur, 20 to 24 pounds glue, 3 to 16 poundsalum, and 2 to 4 pounds potassium nitrate. V

2. A waterproofing solution containing in each one hundred gallons ofsolution in water, 1.2 to 3.7 pounds sodium hydrate, 20

to 28 pounds Japan wax, pound sulfur, 20

to 24 pounds glue, 3 to 16 pounds alum, and 2 to 4 pounds potassium'nitrate.

In testimony whereof I have hereunto set my hand at Brawley, California,this 25th day of June, 1912.

GEORGE W. SNYDER.
